I bought this power bank in August 2019 from Flipkart. I started using it and after opening the product box, I found this too bulky to carry. Its weight is around 300 gms which is too much, even now days when companies are trying to make techy products lighter, in these days carrying 300 gms is difficult and not advisable.
Second thing its power holding capacity is not that Good.
Fast charging does not work as a fast charger works when wall mounted.
The LED light present in the power bank is not that brighter either.
Overall I dont find this product useful.
I would suggest using any different brand than Mi.
Thank You.
